Plans to replace sewer station moving along

DEL MAR — City Council took action on three items at the Nov. 17 meeting that keep plans to replace the aging 21st Street sewer pump station moving forward.
Council members authorized a first-ever wastewater disposal agreement with the city’s largest sewer customer, the 22nd District Agricultural Association, which operates the Del Mar Fairgrounds.
Any changes in use at the fairgrounds can significantly impact the system. The agreement defines flows from the 22nd DAA, allowing design plans to be confirmed and finalized to ensure the new pump station meets projected sewage flow.
Council also approved an additional $14,715 for consultation fees. The money is available in the contingency funds from the project’s $5.4 million budget, which will not increase as a result of the recent council action.
Finally, council approved a resubmittal to the Design Review Board because the project required modifications following completion of an energy analysis. Those changes include a height reduction, the addition of a fence and a surge tank replacing the flywheel design for less energy consumption.
The underground pump station, which was built in the early 1970s, has exceeded its 30-year life expectancy. It handles flow from the majority of the city as well as the fairgrounds. A major failure could result in a significant amount of sewage being discharged into the ocean and lagoons.
Construction is slated to begin late next year or in early 2010. The project is expected to be completed by the end of 2011.
